Abstract: PROBLEM TO BE SOLVED: To provide an air quality activating device which can reduce its vibration and noise while stably generating oxygen-enriched air. SOLUTION: An air quality activating device 1 generates oxygen-enriched air by forcibly feeding air to an adsorbent 54 capable of adsorbing and desorbing nitrogen, and it is equipped with at least two adsorption vessels 21 and 22 in which the adsorbents 54 are enclosed respectively, a scroll compressor 13 to forcibly feed the sucked air to the adsorption vessels 21 and 22 respectively, and a flow route control means which changes over the respective adsorption vessels 21 and 22 to an adsorption stroke and a desorption stroke alternately by changing over the flow route of air discharged from the scroll compressor 13 and, when either of the adsorption vessels 21 and 22 is put into the adsorption stroke, puts the other adsorption vessel 22 or 21 into the desorption stroke.

Title: Manufacturing method of epitaxial silicon wafer
Inventor: NINOMIYA MASAHARU
IPC: H01L21/208
Filed: 1999-09-30
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method superior in IG capability which is complete in a relatively short period by suppressing uneven formation of oxygen precipitation nucleus of an epitaxial silicon wafer provided with the IG capacity, so that no BMD is formed near the surface of silicon wafer. SOLUTION: A potential nucleus is allowed to take place and grow over the entire crystal with a single-crystal silicon to which carbon is added by a CZ method in a low-temperature processing, and then the potential nucleus on the substrate surface is allowed to shrink and dissolve in a middle- temperature processing, while a BMD is grown and formed inside the substrate. Thus, the BMD appears inside the wafer, instead of explicitly appearing at the surface-layer part of it, allowing the variation in BMD density in a crystal growth method to be less under control. If an epitaxial film is formed on the substrate, the BMD is formed only inside the substrate with no surface defect.

Title: Advanced controller
Inventor: DATE YUKI
IPC: G06F9/38
Filed: 1989-10-26
Abstract: PURPOSE:To improve the performance of advanced control by invalidating a detection signal indicating that effective information is held in all register groups which wait to be determined when detecting a following instruction being an instruction which does not update the contents of the registers. CONSTITUTION:When the following instruction is the instruction which does not update the register groups 5 and 6 and effective register numbers are held in registers 19 - 22 with a precedent instruction, 0 is set in an FF 15 by a decoder 14. At this time, an AND gate 24 outputs 1 as a determination wait signal and an AND gate 25 outputs 0. Therefore, even if effective register numbers are held in all the registers 20 - 22 in a register group which waits to be determined, no influence is exerted upon the synchronous control over pipeline processing if the instruction does not update the register groups 5 and 6, and the processing can be carried on. Consequently, the performance of the advanced controller can be improved.

Abstract: PURPOSE:To promptly search for a two-point connecting route by assuming a virtual wiring through an assumed obstacle between the two points, and searching for the connecting route only on the virtual wiring or in a range adjoining to the obstacle as the searching range. CONSTITUTION:An obstacle 12 exists in a semiconductor integrated circuit 10. First a virtual wiring 18 to link a starting point A and a target point B is set.

Next, the new grating cell on the wiring 18 adjoining to the current grating cell is found. Then, whether or not the route can progress to the grating cell found in the former step is checked. Since the grating cell 1 is out of the range of the obstacle 12, the route is judged to be able to progress, and it progresses to the found grating cell 1. Further using the grating cell 1 as the current grating cell, the current grating cell position and condition are checked. When the route arrives at the obstacle 12, it is made to progress along it, and the wiring route is searched for.
